IVT AirX - management of pump operation based on spot pricing

[JanSpacil]

Hi,
I am looking for a solution that can help me control the running costs of a heat pump based on the variable price of electricity - the spot tariff.
I have an IVT AirX170 heat pump and I would like to limit the heat pump's power consumption during a few (2-4) hours of the day when the electricity price is highest.
I am therefore looking for a solution that, based on information from HomeAssistant, will limit the heat pump's operation during the highest prices, or potentially increase heat accumulation during 'cheap hours'.

I have electricity prices available for the next 24 hours in advance and I am able to determine, for example, 3 hours during the given day when I would like to either limit or eliminate the heat pump's power consumption.
The heat pump is connected to two 300L accumulation tanks, both for the heating circuit and for domestic hot water heating. I would like to use these accumulation tanks as energy storage for the time when the heat pump's power consumption will be limited.

Is the EMS-ESP solution suitable for this? Would it be possible to control the heat pump using the EMS protocol in this way?
Both the physical connection to REGO2000 in IVT and the connection with HA should not be a technical problem.

Thank you for your help!

I think so yes. The first thing is to see if your devices (AirX170) can be detected. I know the REG2000 is. Best way is to try it out and create the logic in Home Assistant, and share for others to learn from
